I do not try to answer your question but I want to share some experience with
you concerning the AHA1542CF only. I had tried to make the 1542cf to 8M/s and
install the FreeBSD 2.0.5 950622 SNAP succcessfully (without any complaint
about data lost from the system). My scsi hard disk is microplus 1G disk.
Although the scsi disk is ok for 8M/s but my cdrom (NEC3x1) only4.5M/s so I set
it back to 5M/s.

I would like to know if anyone has successfully made use of the 'fast' 10MB/s
transfer rates of an AHA-1542CF SCSI-2 adapter under FreeBSD.
Our system looks like this:
Cyrix 486Dx2 66
16 MB RAM
EISA/VLB
AHA-1542CF
Seagate ST31230N 1.06 MB SCSI-2
FreeBSD 2.0.5
The AHA's setup is currently setup for 5MB/s transfer and Sync Negotiation
and FAST SCSI options are set to 'no'.
Is the ST-31230N capable of handling more than 5MB/s and Sync Negotiation etc?
ie has anyone sucessfully done it under FreeBSD 2.0.5 ? The BIOS warns that
"most systems don't handle >5MB and that data may be lost etc".
I have been looking for a detailed source on Seagate drives but so far all
I've found is
bite.db.uth.tmc.edu:/computer_info/technical/hd/Seagate
which lists lots of technical details except the stuff that I'm looking for!
Any help appreciated :)
